CROSS-REFERENCE TO RELATED PATENTS

The present U.S. Utility Patent Application claims priority pursuant to U.S. Provisional Application Ser. No. 62/051,118, entitled, “CLAMP DEVICE THAT HOLDS A TOILET BOWL SECURELY TO THE FLOOR WITH OR WITHOUT THE USE OF TOILET CLOSET BOLTS”, filed Sep. 16, 2014, which is incorporated by reference herein and made part of the present U.S. Utility Patent Application for all purposes.

TECHNICAL FIELD

Embodiments described herein relate generally to securing clamps, and in particular to clamps for securing the base of a toilet to the floor without the need for toilet closet bolts. Further embodiments relate to securing the base of a toilet to the floor utilizing toilet closet bolts. Yet further embodiments related to securing the base of a toilet to the floor while significantly reducing the chance of cracking base of the toilet with the tightening of the clamp.

BACKGROUND

Traditionally toilets are secured to the floor using two toilet closet bolts, one on either side of the toilet, whereby the bolts are secured to the floor flange and extend upward through corresponding bolt openings on each side of the base of the toilet. Washers and nuts are then placed onto each of the bolts, whereby the nuts are tightened, and thereby securing base of the toilet in place. One of the problems with this method of securing the toilet is that the nuts can be easily over tightened, which often results in the cracking or breaking of the toilet bowl base. When this occurs, the entire toilet will need to be replaced.

Another problem with this method is that over time these closet bolts often need to be replaced, such as when the bolts corrode, when the home owner needs or desires to replace the toilet, or, when repairing an existing toilet that is leaking around the base.

Toilet closet bolts are labor intensive and time consuming to replace, in part, because the entire toilet needs to be removed from the bolts and set aside. First, the toilet bolt caps that cover each of the closet bolts must be removed. The nuts from each of the toilet closet bolts then need to be loosened and removed. Often, the nuts are rusted onto the bolts, whereby the bolts need to be cut off. Then, the toiled is removed from the bolts and set aside. The old wax ring is scraped from the floor flange to be able to access the bolts. The floor flange is then removed from the floor opening. Then the nuts and washers holding the original closet bolts in the flange need to be removed. New bolts are then inserted into the flange and need to be properly aligned with the location of the original closet bolts. Once aligned, the new bolts are secured to the flange with washers and nuts. A new wax ring and the flange are then installed around the floor opening. The toilet bowl is then lifted and set into place over the newly installed closet bolts. Nuts are then placed one each of the closet bolts and tightened. As can be appreciated this is very labor intensive and time consuming and usually a two person job.

As can be appreciated, a device is needed that can secure a toilet to the floor without breaking or cracking the toilet, and yet can be quickly installed, or replaced by an individual saving hours of labor and time.

Referring now to the drawings, wherein various elements depicted are not necessarily drawn to scale and wherein, through the views and figures, like elements may be referenced with identical or similar reference numerals, there is illustrated various embodiments of toilet clamps for securing or anchoring a toilet to a floor.

As seen in FIG. 1, there is illustrated a rear perspective view of a toilet 100 secured in place utilizing a single screw toilet clamp 110 and multi-screw toilet clamps 120. It is contemplated to be within the scope of this invention that as few as one clamp could be used, one clamp per side could be used per, or various combinations of multiple clamps could be used, depending on a user's needs, preferences, including the size and design of the toilet and the type of flooring to which it is to be secured.

Referring now to FIGS. 2 and 3, with FIG. 2 illustrating two embodiments of toilet clamps 110 and 120 and FIG. 3 illustrating a cross-section view of toilet clamp 110. Clamp 110 includes a generally solid body 111 that includes a single predrilled hole 112, a top surface 114, a recessed portion 132 positioned near and below top surface 114, a floor engagement portion 116, a toilet base engagement portion 118, and an intermediate portion 119 which transitions the bottom portion of clamp 110 between the floor engagement portion 116 and toilet base engagement portion 118. The top surface 114 is convex or partial ball-like in shape and extends between the toilet base engagement portion 118 and the floor engagement portion 116. It is contemplated that the toilet base engagement portion 118 could be made of various materials as well as shaped to facilitate optimal engagement with the shape of the portion of the toilet 100 that the clamp 110 will be in contact with. This includes shaping at least a portion of the toilet base engagement portion 118 to a match the base of the toilet 100 for which it will engage. Similarly, the floor engagement portion 118 could be made of various materials as well as shaped to facilitate optimal engagement with the surface of the floor on which it will be placed. As illustrated in this particularly embodiment, the floor engagement portion 118 has a generally flat or planar portion that then extends in a generally curved intermediate portion 116 to toilet base engagement portion 118. The amount of surface area of toilet base engagement portion 118 that engages with the toilet 100 is of a width and depth to spread the force of the clamping on the toilet out so as to substantially inhibit the cracking or breaking of the toilet when clamp 110 is installed.

Clamp 120 includes a generally solid body 121 and includes two predrilled holes 122 and 123, a top surface 124, recessed portions 132 positioned near and below top surface 124, a floor engagement portion 126, toilet base engagement portion 128, and an intermediate portion 129 which transitions clamp 120 between the floor engagement portion 126 and toilet base engagement portion 128. The top surface 124 is partial ball-like in shape and extends between the toilet base engagement portion 128 and the floor engagement portion 126. As with clamp 110, it is contemplated that for clamp 120, the toilet base engagement portion 128 could be made of various materials as well as shaped to facilitate optimal engagement with the shape of the portion of the toilet 100 that the clamp 120 will be in contact with. This includes shaping at least a portion of the toilet base engagement portion 128 to a match the base of the toilet 100 for which it will engage. Similarly, the floor engagement portion 128 could be made of various materials as well as shaped to facilitate optimal engagement with the surface of the floor on which it will be placed. The amount of surface area of toilet base engagement portion 128 that engages with the toilet 100 is of a width and depth to spread the force of the clamping on the toilet out so as to substantially inhibit the cracking or breaking of the toilet when clamp 120 is installed. Although shown with two predrilled holes 122 and 123, it is contemplated that the number of holes used as well as the overall width of clamp 120 could include 3 or more holes depending on the size of the clamp and upon a user's preference.

The top surfaces 114 and 124 of the toilet clamps 110 and 120 are smooth, rounded and shaped to facilitate the runoff of liquids to at least help keep the toilet clamps clean once installed, and to further facility safety around the toilet by reducing possibility of stubbing one's toe, or by substantially preventing the cutting or catching of one's hand when cleaning around the toilet. The thickness of each of the toilet clamps is such to enable each of the predrilled holes 112, 122 and 123 of clamps 110 and 120 to be angled in a manner such that when the clamps 110 and 120 are properly installed, the holes 112, 122 and 123 are oriented at an angle between being perpendicular to the floor and being parallel to the floor (see by way of example FIGS. 3-6) and to ensure that that the screw will go into the floor at an appropriate angle so as to pull the clamp properly toward the toilet to thereby securely hold the clamp to the toilet and floor.

For the operation of toilet clamp 110, toilet 100 is properly aligned and placed over the wax ring and floor opening. Toilet clamp 110 is place proximate the toilet 100 such that toilet base engagement portion 118 is over and engages the base of toilet 100 the floor engagement portion 116 is proximate to and engages the floor upon which the toilet 100 is placed. Once properly aligned or positioned, a screw 130 is driven through hole 112 and driven into the floor thereby securing clamp 110 to the floor and toilet and thereby securing the toilet to the floor. The angle of the predrilled hole 112 ensures the clamp can be pulled tight to both the floor and the toilet 100 ensuring optimal securement.

Similarly, for the operation of toilet clamp 120, toilet 100 is properly aligned and placed over the wax ring and floor opening. Toilet clamp 120 is place proximate the toilet 100 such that toilet base engagement portion 128 is over and engages the base of toilet 100 the floor engagement portion 126 is proximate to and engages the floor upon which the toilet 100 is placed. Once properly aligned or positioned, a screw is driven through each of the holes 122 and 123, with each screw 130 being driven into the floor thereby securing clamp 120 to the floor and toilet and thereby securing the toilet to the floor. The angle of the predrilled holes 122 and 123 ensures the clamp is pulled tight to both the floor and the toilet 100.

Subsequent to the installation of toilet clamps 110 and 120, the top of each of the predrilled holes 112, 122 and 123 can be capped or filled with material such as a caulk sealant for esthetic reasons as well to prevent liquids and caustic cleaning materials from entering into the holes thereby protecting the screws.

Referring now to FIG. 4, there is illustrated a cross-sectional view of an alternative embodiment of a toilet clamp 410. Clamp 410 includes a generally solid body 411 and includes a predrilled hole 412 for receiving therein a screw 130, a top surface 414, a recessed portion 132 positioned near and below top surface 414, a floor engagement portion 416, a toilet base engagement portion 418, and an intermediate portion 419 which transitions the bottom portion of clamp 410 between the floor engagement portion 416 and toilet base engagement portion 418. The top surface 414 is partial ball-like in shape and extends between the toilet base engagement portion 418 and the floor engagement portion 416. It this embodiment the toilet base engagement portion 418 is generally planar and includes attached thereto a non-slip material 425, such as, but not limited to rubber, to further secure clamp 410 to the toilet to which it is connected. Although illustrated on the generally planar surface of the toilet base engagement portion 418 it is contemplated that the non-slip material 425 could be utilized on any of the embodiments of the present invention.

The floor engagement portion 418 could be made of various materials as well as shaped to facilitate optimal engagement with the shape and texture of the surface of the floor on which it will be placed. As illustrated in this particularly embodiment, the floor engagement portion 418 has a small hump 426 positioned near the outer perimeter of clamp 410 and a generally flat or planar portion 427. Planar portion 427 can be angled at a slight upward incline, such that when the clamp 410 is installed, and hump 426 engages the floor and the screw is tightened, the slight upward incline of planar portion 427 will not be in contact with the floor, but the clamp will be secured to the floor and toilet. The amount of surface area of toilet base engagement portion 418 that engages with the toilet 100 is of a width and depth to spread the force of the clamping on the toilet out so as to substantially inhibit the cracking or breaking of the toilet when clamp 410 is installed.

Clamp 410 further includes a cavity 430, which can be place over an existing toilet closet bolt. This provides a user the option of not having to remove an existing toilet closet bolt prior to the installation of clamp 410. Although illustrated as a cavity, it is contemplated that the cavity 430 could extend all the way through to the top portion of clamp 410.
